Compared
nokko vs Toggl Track, for billing the hours.
Toggl Track is a time tracker with reports and invoicing in Toggl's cloud, and a desktop app that needs a Toggl account. nokko's timer writes the session into the task's own Markdown file on your Mac, and the projects, the timeline and the invoice are in the same app, with no account at all.
If you need team reports and approvals across many people, keep Toggl.
Toggl Track is good at what it does: a fast timer everywhere, reports across a whole team, approvals, and integrations with the project tools a company already uses. nokko does not do team-wide time reporting with approvals, and it has no integrations; it is one app for a few people whose hours become their own invoices.
If the hours should live next to the task, and the invoice next to the hours.
In nokko a timer is started on a task, from the Mac, the menu bar, a widget or the iPhone's Lock Screen, and stopping it writes a ⏱ line under that task in the project's file. The Time view sums the sessions by client, project and day; the Clients view shows what is not yet invoiced; and the invoice is drafted from those hours with rates, VAT and a PDF, as another file you own.
There is no Toggl workspace to keep in step with the project tool, because the project tool is the same app. And there is nothing to log in to: the hours are in files on your disk, readable in any editor, for as long as you keep them.

No automatic tracking, no Toggl import, no integrations.
nokko does not watch which apps you use; its timer is one you start. It does not import Toggl's history, so the timer starts fresh and old reports stay in Toggl. And it does not plug into other tools: its interoperability is the file format, which Obsidian and any text editor read.
